    Sorry for the off topic, but how well does the Gibbz upper fit with the a
    Aero lower?

    No worries, this gives me a chance to gush over my AR a bit despite the issues...if you're asking me, the fit is excellent.

    Something I like to do when zeroing if I will reuse the same target is to use a permanent marker, paint marker or thick tipped pen to mark groups on the target as I shoot them. Now, if you're doing it all through the spotting scope, you can mark them after the fact if you're saving the target for reference. If I assume you are firing 3 rd groups and that you wish to be zeroed dead center on the X, it looks like you might be a 1/10 mil high, windage looks good. Your lowermost round is right on, but the group average taking into account the nearest two rounds above that is just a shade high. Punch three through a fresh target and see what you get. Ultimately, being 1/10 mil off at 100 meters (I am assuming the distance as well) is probably a non-issue.

    What I assume is the last three shot group looks pretty tight too, so you got that in the plus column as well.

    That's your gas block journal diameter on the barrel. I was asking about the gas port diameter. They are usually .068" to .094". We're talking about the tiny hole cut into the barrel to bleed gas that will cycle the action. I also can't see what gas system length you have. Is it CLGS, MLGS, or RLGS?

    Sorry it took so long to respond I've been waiting on some new parts, pistol grip and stock. I have CLGS, my gas port is a .136
